The thing which controls what will shoot well in your rifle is the twist, most 45 caliber guns are either 1 in 20 or 1 in 28. The 1 in 20 requires long heavy bullets for the best accuracy, the 1 in 28 is what is considered normal and will usually shot well with 180 gr to 220 gr and some people stretch that considerable in both directions.
My personal recommendations would be the 180 gr Deep Curl or Gold Dot and the 200 gr Shock Wave or SST the Lehigh also 200 gr is my most accurate. Personally I stay away from overly expensive unjacketed bullet.
